The corresponding low frequency bandwidth of a is about 2 〇〇 MHz (VSWR < 2), b corresponds to about 23 〇〇 · , VSWR < 2 · 5). In order to meet the needs of higher standards in the future, it is still necessary to improve the above-mentioned multi-frequency antenna construction to have a larger bandwidth in both the low frequency and the high frequency portion. [New content] The purpose of this innovation is to provide an improved multi-frequency antenna to increase the bandwidth of conventional antennas, which can increase the maximum sensitivity by increasing the _ volume. According to the above object, the present invention proposes a multi-frequency Η-type antenna, the multi-frequency η-type antenna structure includes a conductive radiant portion, a conductive ground portion, a conductive connecting portion and a _ coaxial electric easing; wherein, the conductive light beam 6 M288014 The portion includes a left section, a right section, and a τ-type structure, the conductive connection portion includes a first portion, a second portion, and a third portion, and the conductive connection portion is respectively connected to the conductive radiation portion and the conductive ground portion; and the coaxial cable It is then a conductive point that is electrically connected to the conductive connection. [Embodiment] In order to explain the innovation in more detail, a preferred embodiment of the innovation will be described below with reference to the drawings. As shown in the third figure, the plane 囷 shows a preferred embodiment of the innovation, the multi-frequency Η type antenna 30 includes: a conductive radiant portion 320, which is presented in the state of a line, and extends longitudinally, with corresponding left and right The left section 322 and the right section 324 of each end, and a Τ-shaped structure 326 are connected to the conductive radiating portion 320. The Τ-shaped structure 326 is located above the left section 322 and the right section 324 for increasing the Η type. The bandwidth of the antenna, the 结构-type structure 326 has a segment 3262, 3264 and a transmission line 3266; a conductive ground portion 330 is vertically separated from the conductive radiation portion 32; a conductive connection portion 34 is located at the conductive Between the radiating portion 32A and the conductive ground portion 330, the first portion 342, the second portion 344, and the third portion 346 are included, and the first portion 342 and the second portion 344 of the conductive connecting portion 340 extend perpendicularly to the conductive radiating portion, respectively. 320 and conductive ground portion 33A. The first portion 342 of the conductive connection portion 34 is electrically connected to the conductive radiation portion 32Q, the second portion 344 of the conductive connection portion 340 is electrically connected to the conductive ground point 330, and the third portion 346 is respectively connected to the first portion 342 and the second portion 344.
